MI K-CAN OR ANALOGOUS RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 526,460, datedSeptember 25,1894. Application filed July 18, 1395 $eria1No. 517.90% t)odem To all whom it may concern:

Be it known that I, FREDERICK O. J. Ronn IIAU, a citizen of the UnitedStates, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Milk-Cans or AnalogousReceptacles, cation.

This invention relates to milk cans and.

other portable receptacles, and is designed to provide certainimprovements in such articles which will be hereinafter fully set forth.

Heretofore milk cans have been constructed with cylindrical bodies, tothe bottoms of which have been riveted inwardly bulging flanged heads,whereby the lower end of the can consists of an annular edge composed ofthe metal of the side and bottom pieces, and aslighthollow within thisedge. In handling such cans it is frequently customary to drop them withmuch violence on the pavement, and in transporting them it is usual tostand them side by side on the floors of Wagons. The violent shock towhich they are :sub- Jected necessitates much strength of construction,and consequently so great a weight of metal is employed that the cansare unduly heavy. When transported in .wagons, the arring of the cansnot only Wears away the wagon floor, but also causes much disagreeablenoise. To overcome these disadvantages there has been provided a rubberor spring cushionfor the bottom of such receptacles, which served alsoas a sound deadener therefor. The cushiontempers the shocksdue todropping the cans, diminishes the wear on the cans, and the Wear by thelatter on the wagon floors, and the sound deadener prevents vibrationand greatly diminishes the noise incident to transportation of the cans.

My present invention provides certain improvements in the application ofsuch cushions to the cans which will be hereinafter fully set forth.

In the accompanying drawings, which illustrate the preferred form r ofthe invention, Figurelis a perspective view of a milk can provided withmy improvements. Fig. 2 is a bottom plan view thereof partlyinhorizontal section and showing part of, the rubberbroken away. Fig. 3 isa fragmentary axial section thereof out on the line 3-3 in Fig. 2 and ofwhich the following is a 's'pecifi-i looking in the direction of thearrow. Fig. 4 is a fragmentary axial section thereof cut on the line4-4= in Fig. 2 and looking in the di-' rection of the arrow. Fig. 5 is aplan view and cross-section of the rubber ring removed,

and Fig. 6 is a plan view of the clamping ring removed.

Referring to the drawings, let A indicate 6c the can as a whole; B, thebody thereof; 0, the bottom thereof; D, the bottom flange thereof, and Ethe cushioning and sound deadening device.

The can A may be any usual or suitable construction of portable metalliccan, that shown being the usual milk can, "the body B of which iscomposed of cylindrical sheet metal, and the bottom 0 of which is asheet metal head having concave outwardly bulging 7o center a, andflanged edges 19, which are united .byrivets c to the lower edge d ofthe cylindrical part D. The rivets c, or any suitable substitutetherefor for fastening the two parts together, extend around the loweredge 7 5 in suitable manner to contact with the floor 86 upon which thecan may be dropped, so as to receive the force of the concussion andgraduate or cushion the shock in transmitting this force to the body ofthe can. The cushioner should be of yielding and elastic material,

and properly fixed to the body of the can. As heretofore I construct thecushioner to also serve the function of a sound deadener, for whichpurpose it is constructed of a nonvibratory material. Indiarubber, or acom- 0 position containing a considerableproportion of rubber, bestserves both these purposes, and thereforeis what I prefer to employ forthis device.

According to my. improvements for attach- 5 ing the cushion to the canIprefer. to provide a-detachable connection between the two of theconstruction shown, which connection con sists preferably of a support Ffor the cushion maintaining it in vertical position, a

clamp G for the cushion preserving it against the can, studs H carryingthe support F and guiding theclamp G, and bolts I for adj usting andholding the clamp. The support F is preferablya flat-annular ringfitting within the space J in the bottom of the can, and loosely mountedthereon. The studs H may be of any construction suitable for preventinginward movement of the support F. I prefer to form these studs asinwardly projecting radial pins having headed outer endsfixed in holes ein the flange D, and cylinelongated holes 9, through-which one of thebolts I passes, and intermediate of these ends it has other bolt holes hfor the other bolts I. The lower edge of the clamp G is preferably flushwith the bottom edge of the flange'D, and the clamp extends upwardlywithin the space J preferably beyond the upper edge of the cushioningmaterial E and its support F. Near its upper edge the clamp ispreferably constructed with guide holes 1', through which the inwardlyprojecting ends of the studs H pass, whereby these studs are reinforcedat their inner ends by the clamp, and the latter is guided and in partmaintained in position by the pins. The bolts I maybe any suitableconstruction of bolt, but I prefer to construct them as headed boltshaving shanks j tightly seated in and passing through holes kin theflange D between the rivets'c'and the studs H, and having screwthreadedends on which screw nuts 1 against the'i'nner face of the clamp G.Preferably the bolts I are arranged radially and intermediately of thestuds H.

The cushioning material E is preferably a molded endless annular ring orstrip of rubber of rectangular cross-section, and less width thanheight, designed to'fit in the rectangular space within the flange Dbeneath the support F and-exteriorly of the clamp G, and to project asufficient distance below this space to give the requisite cushioninghearing. The rubber ring shown is constructed with radial holes m,ninety degrees'apart and near its upper edge, through which holes theshanks j of the bolts I pass.

In using my improvements according to the construction shown,the studs Hand boltsI are permanently fixed to the can by being driven home intheir respective holes in the flange D. The supporting ring F is placedupon the studs H before the bolts are driven'home, and is then retainedin its position against loss before the parts are all assembled. Therubber ring E is then sprung with its holes an over the shanks of thebolts, whereupon the clamping strip G is placed within this ring:and'expande'd until its holes g h engage the bolts, and its holes '5the studs. The nutsl are then screwed tightly against the ring, firstthat diametrically opposite the overlapping ends f, then the two on eachside,'and finally the nut bearing directly against these ends. In thisway the clamp is drawn very tightly against the ring, compressing theupper portion of the latter in the space above the rivets c, whereby thering is held firmly and permanently in position. As the clamp is drawnhome, its overlapping ends f slightly separate until its final positionis reached. When the rubber ring is thus clamped tightly against thesides of the can, it greatly decreases the vibration thereof, and hencereduces the noise emitted when the can is jarred or struck. Byprojecting at its lower edge below the can,

it takes up most of the shocks to which the can is subjected, andrenders its'transportation much less noisy thanformerly. -When the canis thrown or dropped from one" place to another, the cushioning of thespring graduates the resulting concussion, and "correspondingly reducesthe strains to which the can is subjected, thereby permittingthe use ofa lighter material in its construct1on; and

a consequent decrease i-nthe weight of the can itself.

It will be seen that my invention provides an improvement in portablecans and like receptacles, which is simple and effective andparticularly advantageous when used with metallic milk cans, and it willbe understood that th-einvention is not limited to the particularconstruction and arrangement of the partsiset forth as constituting thepreferred form of the invention, as it may be employed withsuchmodifications of the various parts,

or with such equivalents thereof, as circumstances or the judgment ofthose skilled in the art may indicate. w

I prefer to construct the supporting ringF andthe clamping ring G ofthin malleable cast i'ron,but any suitable sheet metal or other materialmay be used instead.

What I claim is- 1. In a can having a hollow bottom and a surroundingedge having radial boltholes, a

cushioning material surrounding the inner side of said edge and havingthrough its body radial bolt holes corresponding to those therein, anannularmetallicclamp at the inner side of said material clamping thelatter against said edge and having radial bolt holes corresponding tothose in said material, and bolts drawin-gisaid clamp toward said edge,traversing entirely through said holes through said edge, clamp andthe-body of *saidcushioning material, preventing displacement of thelatter, and drawing said clamp thereagainsh sub- 'stantially as setforth.

space J, and a bottom edge D having radial bolt holes, in combinationwith a ring E of cushioning material,having radial bolt holescorresponding to those in said edge D,asupport F at top for said ring, aclamp G within said ring and clamping thelatter against said edge D,said clamp consisting of a substantially vertical metallic ring havingradial holes corresponding to those in said ring E, said ring Eextending above and below the lower edges of said clamp G and said edgeD, and bolts I traversing said ring E, through said holes and throughsaid edge D, and clamp G, drawing the latter toward the former andpreserving said ring E in position, substantially as set forth.

4. In a can, the bodyB and head 0 having bottom edge D and hollow J, incombination with the rubber ring E within said edge D, the support Fwithin said space and at top of said ring, the studsH above saidsupport, and a clamp G at the inner side of said ring E clamping thelatter against said edge D, and

annular edge D and bottom hollow J, in combination with the rubber ringE within said hollow, the clamp G consisting of an annular strip ofmetalhaving overlapping ends f, having coinciding elongated holes g insaid ends, and bolt holes h intermediate of said ends, said clampengaging the inner face of said ring E, and boltsI traversing saidclamp, and the body of said ring engaging said edge D, drawing saidclamp against said ring, and thereby clam ping the latter against theinner face of said edge D, substantially as and for the purpose setforth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
